I liked Ramez Naam's Nexus and Crux novels. He was up for the Campbell award in 2013 & 2014. They're about a guy that figures out how to take injected nanomachines and turn them into something that is akin to telepathy or empathy (not sure whether the nanomachines would be able to make it past the blood barrier, but this is SF after all). It's possible that people can use this technology to control other people, and the US government either wants to shut it down or control it. The (final? next?) book in the series is out in May.
